Hello and thank you for the responses.
I offer food frequently, and put her on the puppy pad after every nap or meal so she can go. At night, she sleeps with me (she's really good and settles right down when the lights go out, and only gets up once or twice needing to pee).
She poops about once a day; it's a really dark brown but not black, so I think that's okay?
I feed her Wellness. I crush up the dry food with a mortar and pestle and soak it in water to keep her hydrated. She's not super fond of the food, so I sometimes throw some bits of grass-fed beef in, or some meat juices on top to make it more appetizing - should I just go get wet food and see if she likes that better? She really isn't eating very much, but I have to remind myself she's still not even 2 lbs. ...and anyway, everything seems to be in order. I've just begun tracking her weight to make sure she's on the up and up.
I've been taking her out and introducing her to people (but no dogs). She's so cute; she's the life of the party, and she's really good with everyone. I've been trying to get as great a diversity of people to interact with her as possible. So far, so good.
She naps often, but she's very alert and playful when she's awake, so it's probably not lethargy. I'm just so paranoid of parvo...
I really want to get her to meet other dogs, I just don't know many people who own dogs, so it's hard to do it safely, yanno?
Anyway here's a photo of her.
Thanks again for reading.
